Company Profile

Midori Precisions Co., Ltd. was founded in 1952 as a manufacturer of electro-mechanical transducers.

These early products were created by the wire-wound potentiometer technology to be offered in the precisions instrumentation markets.

In 1962, Midori developed technology that enabled the company to launch the precision conductive plastic potentiometers, which are called the Green Pot products.

In 1973, Midori pioneered another technology, the contactless magneto-resistive potentiometer (the Blue Pot product line).

In 1994, Midori introduced the position sensors (the Orange Pot product line) which adapted the Hall Effect IC as sensing element and improved the key functions and cost efficiency.

Lately, Midori has been focusing on the development of another product line, Digital Sensor/Encoder to ensure its leading position in the market and further create new customer bases globally.

Midori, with its ISO 9001 certificated quality control system, offers position sensing solutions essential to the aerospace, automotive construction, marine, off-road machinery, manufacturing automation, and medical equipment industries around the world and continues to provide quality and service second to none in its industry.
